Polygonatum prattii is one of my favourite of the genus. I currently grow P. hookeri, P. falcatum, P. prattii and soon P. aff. graminifolium. The Chinese Polygonatum are delightful. I look forward to their appearance every year, as it is amongst some of the later plants to make their debut in the garden. They are a north temperate genus of approximately 60 (39 in China, half endemic. They are rhizomatous perennials with pendulous flowers, solitary or clustered at the nodes. Prattii is 30cm and comes from w. to sw. Sichuan, and nw. Yunnan.
